Lithuanian Last names in Newburgh, NY area

Re: Lithuanian Last names in Newburgh, NY area

I know that they immigrated to America and changed there name Parker before my great-grandfather was born, there's the problem I can't find there immigration records because the records have there original Lithuanian last names my grandpa knows them I think.

My great-grandfather was born 1913.

I'm 4th generation of that family born in America according to my grandfather.
